What we claim as our invention, and desire to secure by Letters Patentof the United States, is.:-

1. The process of coating paper, glass or other material with a mixtureof collodion solution and powdered metal which consists in applying saidmixture to the material, passing the coated material through water,whereby the solvent is absorbed by the water and the residual coatingfixed, and subjecting the coated material to pressure.

2. The process of coating paper, glass or other material with a mixtureof 'collodion solution and powdered metal which consists in applyingsaid mixture to the material, passing the coated material throu h water,whereby .the solvent is absorbedgr by the water and the residual coatingxed, and subjectin the coated material to pressure while un er water.

3. The process of coating paper, glass, cr other material with amixtureof collodion and powdered metal, which consists in applying saidmixture to the material, causing the latter to travel during theapplication of the mixture, subjectin the coated material to the actionof co1 water flowing in the opposite direction to the direction ofmovement of the material and in contact with the material whereby thesolution will be absorbed and the residual coating fixed and finallysubjecting the coated material to pressure while under water.

In witness whereof we have signed this specification in the presence oftwo witnesses.
